Wavelength electromagnet waves. 1 of 28 What can they mostly pass through? The body. 2 of 28 What are they not? Strongly absorbed. 3 of 28 What are radio waves are thought not to have an effect on? On the health of living tissue. 4 of 28 What are microwaves? Radio waves with short wavelengths. 5 of 28 What are they slightly absorbed by? The body 6 of 28 What effect can they have on the body? A heating effect. 7 of 28 What do phones produce? Microwaves. 8 of 28 Have microwaves produced by phones been proven to cause health problems? No. 9 of 28 What are the infrared waves absorbed by and to what extent? The skin to a limited depth. 10 of 28 What do infrared waves do? Transfer their energy to the skin tissue and warm it up. 11 of 28 What is this heating effect detected by? The temperature-sensitve nerve ending in the skin. 12 of 28 What will happen to meat if it absorbs too much energy? It becomes burnt. 13 of 28 What happens to the skin if it absorbs too many high-energy infrared waves? It becomes burnt. 14 of 28 What do eyes detect? and does it pose any health risks? Visible light and normally no. 15 of 28 What can damage you eyes and even blind you? Bright light. 16 of 28 What should not look a the Sun through? A telescope or binoculars 17 of 28 What are lasers? Intense sources of visible light. 18 of 28 Why are lasers used in light shows? Because they are not powerful enough to cause harm but should be used safely. 19 of 28 What can some lasers do? Cut through materials such as metal.It would also be able to burn through living tissue. 20 of 28 What do ionize waves have enough energy to do? Ionize atoms in materials. 21 of 28 What do ionizing waves have effect on and how? Living tissue by killing or damaging DNA. 22 of 28 What are Ultraviolet rays absorbed by? The body. 23 of 28 What can skin tissue be ionized and damaged by? The shortest-wavelength ultraviolet radiation. 24 of 28 What can ultraviolet radiation cause? Skin cancer. 25 of 28 What can X-rays pass through without being absorbed? Soft body-tissue such as muscles and denser tissue such as bone 26 of 28 What can bone absorb and do? Some X-rays and can be ionized. 27 of 28 What can gamma rays pass through and very high waves do? Body and ionize atoms in living tissue. 28 of 28
